Applicatiomfiled February 1, 1924. Seria1.Nio. 689,869;

This inventionis a device for firmly and rigidly channel-bar members,each] having down turned ends secured. to suitable support ng elements;In. order. to bend the ends of the channelrbar. supporting members, itis f rst necessany. to, heat them and the operation,

therefore requires some little time and labor. It has also been found inpractice,

that: some inconvenience is experienced in fastening the shelf tothebracket or support, so that the shelf. will; lie perfectly flat, and

@not bind or buckle due tothe ordinary warping tendencies of thelumber.

It is tobe understoodhow ever, that,thisconstruction is selected, merely for illustrative purposesand theinvention 1s not limited to. use inconnection there- With. a v

The shelves B are supported by carrier members-G, the ends of which.rest, upon and are secured to bracket members Di. Each carrier memberconsists of a body of channel iron, the-length oify whichcorrespondstothe widthof the shelf, the flanges 15 being slotted at 116,and extending into kerfs 1? formed in theundersides of the shelves,contiguousvto their end edges. The l It is bottom, Wallor" the carriermembers C is struct upwardly to, form a longitudinally disposedconcavo-conven strengthening rib; 17,, )rovided,with spaced apartholes18 contiguous to each endl.

The bracket member D is provided ,With flanges 19,,Wl1l0l1 embrace thesides of' one of the upright support nembers the device being held, inplaceby means of a screw or the like, passed through, a suitableopening.20 in the body of, the, support. The upper .bers G, by passing the lugs22- upwardly beneathtthe rib 17., andacansingthereduced:

ortions. to! protrude through the hQ1es1 a fit) whereupon they areriveted to prevent separation. In this manner the members C and D aresecurely united and a very rigid structure is provided.

The underside of each shelf B, contiguous to each of the kerfs 17, isprovided with recesses 24 in each of which is pivotally mounted alocking member 25. constructed with a minor and a major axis. as shown.Said locking member is preferably made of thin metal having struck-upportions 26, and is retained in position by means of a screw 27. Theslots 16 are so located in the bracket member C as to coincide with therecesses 21.

In practice, before the shelves are placed in position upon the shelfsupports, the locking members 25 are adjusted to have their major axesaligned with the kerfs 17. Then the shelves have been placed in positionupon the members C, with the flanges extending into the contiguous kerisof adjoining shelves, a rotation of a latch piece on the pivoting screw,will cause an end thereof to engage the contiguous slot 16 of thesupporting channel, and thus lock the shelf down to the channel. Byforming each latch piece 25'witl1 a cam edge as shown, it will not onlyhold the shelf down, but also exert a drawing pressure as it is turnedinto engagement with the slot 16. The struck-up portions 26 provide earsor lugs which may be engaged by a suitable tool to assist in rotatingthe device.

A slight modification is illustrated in Figure 6, in which thelongitudinal rib of the carrier member C is provided with a slot 30, toreceive a lug 31, formed on the attaching device 32, secured to theshelf B. In practice the shelf, as it is placed in position, brings thelug 31 into register with the slot 32, so that it will pass through thelatter. Said lag is then given a slight twist to bring it crosswise ofthe slot 30, as illustrated in dotted lines.

The advantages of the invention will be readily understood by thoseskilled in the art to which it belongs. It will be particularly notedthat a very rigid form of shelf support is provided, which may be moreeconomically manufactured than the device disclosed in the applicationfor patent above identified, and while capable of general use. may bereadily substituted therefor. It will also he observed that simple andetiicient means are provided by which the shelf may be fastened to thesupport so as to lie perfectly flat, and also preventsubsequent bucklingor warping of the shelving after it has been placed in position.

Having thus explained the nature of the invention and described anoperative man- 'ner of constructing and using the same, al-

though without attempting to set forth all of the forms in which it maybe made, or all of the forms of its use, what is claimed is 1.
